rlhis invention relates to a wheel'iiange oiler, andmore particularly to a device for delivering oil onto the flange of acar wheel,

oil, is mounted means wherebye this o1l being in turn delivered by the Han e to a switch point, a frog point, fa guard pall, or the side of the regular'track rail'.

A receptacle, holding a certain quantity of on the rail, at that side thereof where the wheel Hange travels. A rotatable roller is yieldingly supported in this receptacle so that its lower portion projects into the bath of o il, and its upper portion projects into the path of travel of the wheel flange. Pawl and ratchet, or equivalent means is provided whereby the roller 1s caused to rotate whenv depressed against its yieldable supports. When a car. passes thereover, the wheel flange will throw the roller downwardly, thereby causing it to rotate and throw oil upwardly onto the wheel flange.

After one revolution, this oil will be delivered to the switch point, or other device where lubrication is required, and the oil receptacleis positioned at such a dlstance from the switch point to be oiled that the wheel will make approximately one revolution while traveling from one to the other. The primaryobject of this inventlon is to rovide a wheel flange oiler, operating as ri'ely described hereinabove, and as described in more detail in the description which follows:

Another object is to provlde improved means for mounting this oiler on the side of the rail.

Another object is to provide such a wheel Hange oiler embodyinga revoluble roller.

Anotherfobject is to )provide improved means for causing the ro er to rotate when depressed into the oil.

Another L object is to provlde improved means for yieldingly mounting this roller in the oil receptacle.

' Another object is to provide improved means for adjusting the roller transversely of the receptacle, that is toward or from the side of the rail head. l f

Another object is to provide improved one or more oil delivering rollers may` selectively mounted and "spacedowithin the same oil'receptacle.

, Other objects and advantages of this invention will be more apparent from the fol# lowing detailed description of one approved form of the apparatus.

The improved wheel flange Yoiler comprises an elongated receptacle, closed at its sides and ends, but substantially open at the top, the bottom 1 of the receptacle being preferably shaped to conform to and rest upon one flange 2 of the rail base of a standard railway rail, and one side wall 3 being shaped to rest against'the vertical web 4 of the rail, this side wall extending upwardly to approximately the under side of the rail head 5. Side wall 3 terminates in an inturned horizontal flange 6, which functions as hereinafter described. The opposite side wall 7 of the receptacle may be given any desired conformation, `but is substantially parallel with the inner side wall 3. and extends upwardly to the level of the lower s/urface of, flange 6. Any suitable means may be used to secure the oil receptacle in place on the rail, as here shown a flange 8 extends from the bottom wall 1 and side wall 3, beyond the end wall 9, and a clamp member 10 is provided for securing this flange 8 to the ange 2 of the rail base. The clamp member 10, as here shown, is similar in construction and operation to a one-piece railanchor, for example, the patent to Fair, 1,364,263, granted January 4, 1921. Other forms ofvclamps might be used, or the flange 8 could be bolted directly to the rail flange 2 0r the vertical web 4.

-Projectin inwardly from each of the side walls 3 and of the receptacle are a plurality of opposed pairs of guide ribs 11. The vertical passage or guideway 12 between one the anchor disclosed in 10o side -wall 7, by means of bolts 15, as indi-l way 12 between al pair vof ribs 11l o'n the op- 'posite side wall of the receptacle. The upper cated in Figs. 2, 4 and 5. Thimbles 16 are adapted to slide up and down in the passages 12, and are normally held at the top of those assages in contact with thelanges 6 or 13 y means of supporting springs 17. In the form here shown, each spring 17 comprises a downwardlyI slanting end portion 18 which engages with the bottom wall of the recep- -tacle, an intermediate coil 19, and an upwardly slanting end portion 20 which projects through a slot 21 in one of the guide ribs 11 and extends beneath the thimble 16 to act as a yielding support therefor. Preferably a pair of similar springs17 are used to support-each thimble 16, these springs projecting inwardly through the two guide ribs 11, in opposlte directions. Lugs 22 may project from the adjacent side wall of the receptacle into the coils 19 of the springs to hold the springs in place beneath the thimbles 16. A short horizontal shaft 23 has its endvportions journaled in the thim` bles 16l for free rotation, and a-solid, preferably metallic roller 24 is mounted on the shaft 23. This roller 24 is of such size that when the shaft 23 and thimbles 16 are held up alglainst the stops 6 and 13 by the springs 17 t e upper portion of the roller will lie adjacent the head 5 of the rail and in the path of travel of the flange 25 of a car I the roller, and between. the roller and the.

wheel, (see Fig. 6). In order to properly adjust the roller 24 toward or from the rail head 5, a -plurality of spacing washers 26 are placed on the shaft 23 at either side of ends of the fthimbles' 16. By varying the number of washers 26 'used at either side of the roller, the roller can be adjusted toward or from the-rail head, as desired. When in this elevated position, the lower portion of the roller 24 projects downwardly into the bath of oil in the receptacle, but there is sufficient clearance between the roller and the bottom of the receptacle to permit the roller to be depressed, against the lresistance of the springs 17, when a car/ wheel passes thereover.

On either one, or both, side Vfaces of the roller 24, a circular seriesof. ratchet teeth 27 is formed and a vertically projecting pawl 29 pivoted at its lower end 30 within the receptacle has Iits upper end 31 held yieldwith the teeth 27 byv ingly in engagement means of a spring 32. This spring 32 may be of the coil type here shown, or of any other equivalent or suitable form. It is obvious that the pawl or pawls 29 will permit the rroller 24 to` rotate freely in one direction, but will prevent rotation in the opposite direction. When the roller 24 is pushed downwardly, or depressed into the oil bath, the engagement of the pawls 29 with. the ratchet teeth 27 will enforce a rotation of the roller 24 in a clockwise direction, as shown in Fig. 6.

In operation, as each car wheel passes over the oilingl apparatus, the flange 25 of the wheel will strike the roller 24 and throw it downwardly against the resistance of the springs 17 and the pawls 31 by means of their engagement with ratchet teeth 27 will cause the roller 24 to spin within the oil. The sudden depression of the roller 24 will splash oil upwardly onto the flange 25 of the wheel, and the spinning roller will also throw upl oil by centrifugal force. When the wheel has passed by, the-springs 17 will return the thimbles 16 t0 their elevated position against the stops 6 and 13, thusraising the roller 24 again into position to be struck by the next car wheel flange.` This device, as here shown, will oil about eight inches of the circumference of the wheel flange, which will in turn oil about that much of the track rail one revolution beyond the location of the oiling device. The oil receptacle should, therefore, be located on the track a distance equal to approximately one revolutionof the wheel in advance of the track section or switch point which is to be oiled.

A greater distance on the wheel flange may be oiled by placing -these rollers in series. In the example here shown, three sets of guide flanges 11 are arranged at spaced intervals in the elongated oil receptacle. When only one oiling roller 24 is to be used, this will ordinarily be positioned in the central sets of guides, asshowmin the drawings. If more than one roller is to be used,

these additional rollers will be mounted in' vices can be assembled in an obvious manner within the guides 12 and then secured in place by the angle stop plates 13, heldin place by bolts 15.

As an alternative construction, the ratchet teeth 27 on roller 24 might be oppositely directed, and the pawls 31 mounted at the opposite side wardly into engagement with the ratchet teeth. In this construction, the roller 24 would be rotated when thrown upwardly by the spring 17, after ,having been depressed by the wheel ange.
